--- Quote from: Ansa89 on January 26, 2012, 03:44:31 am ---The problem is that it searches for "aa484e11-7e4d-4a38-b140-3a5531181bc6" as root partition (this should be the uuid of GA root partition), but as we can see it isn't.
Try to replace "aa484e11-7e4d-4a38-b140-3a5531181bc6" with "/dev/sda3" (without quotes).

Thanks Ansa89 - I tried just what you suggested - same result. I tried a few other things also. First I removed the search line:

 menuentry "Groovy Arcade Linux (on /dev/sda3)" --class gnu-linux --class gnu --class os {
   insmod part_msdos
   insmod ext2
   set root='(hd0,msdos3)'
   linux /boot/vmlinuz root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=LABEL=/GA doscsi video=DVI-I-1:640x480ec
   initrd /boot/initrd

response is this:

    error: unknown file system
    error: you need to load the kernel first

Notice unknown vs. no such? I think grub found it, but it's "unknown." I have no idea...



Ansa89:
I'm not really expert of grub2, but here

--- Code: --- set root='(hd0,msdos3)'
--- End code ---
you try to load a dos partition instead a ext4 partition.
Try this

--- Code: --- menuentry "Groovy Arcade Linux (on /dev/sda3)" --class gnu-linux --class gnu --class os {
   insmod part_msdos
   insmod ext2
   set root='(hd0,3)'
   linux /boot/vmlinuz root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=LABEL=/GA doscsi video=DVI-I-1:640x480ec
   initrd /boot/initrd
--- End code ---
And if you feel lucky, also this

--- Code: --- menuentry "Groovy Arcade Linux (on /dev/sda3)" {
   set root='(hd0,3)'
   linux /boot/vmlinuz root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=LABEL=/GA doscsi video=DVI-I-1:640x480ec
   initrd /boot/initrd
--- End code ---

Spacedueler:
I tried all variations of what you suggest - still with the same results. I even tried from the grub command line as simple command:

   grub> linux  (hd0,3)/boot/vmlinuz

It spits back "unknown file system" If I eliminate the "boot" location (just for experimenting) and enter:

   grub> linux  (hd0,3)/vmlinuz

I get "file system not found" - I've concluded that grub finds the partition and files, but sees them as "unknown" for some reason. I also confirmed the partition and files are there by booting to Ubuntu and using the file manager to locate them. Is it possible this is a grub2 issue? This version is 1.99 - installed with the latest Ubuntu (11.10). Groovy Arcade did run on my system from the liveCD.

Ansa89:
One more try: from grub command line write these commands (in this order)

--- Code: ---insmod ext2
set root='(hd0,3)'
linux /boot/vmlinuz
--- End code ---
